It depends on what you C shell scripts are doing. If they are simply
invoking R, then you can install R, and the required packages, on the
Windows PC and then use batch files under Windows to call your
scripts. Running R in the background on Windows is not a problem.

I checked your data. Now I have to get some sense out of your code. You do :
G - vowel_features[15]
cvc_lda - lda(G~ vowel_features[15], data=mask_features,
na.action=na.omit, CV=TRUE)
Firstly, as I suspected, you need to select a column by using
vowel_features[,15] . Mind the comma!

Here is the answer to your second part. You can use the one file and
look for some type of indicator between each section. I used the
example you sent:

In readLines(/temp/tempxx.txt) :

The easiest way (I use WIndows) is to start each session without
loading the previous workspace. I explicitly save what I need and
then explicitly restore it. In most cases, I always reconstruct the
data I need.
I use the '--no-restore --no-save' options.

A few ideas:
Make a log-scale y-axis like:
hist(my.data,...,log=y)
argument yaxp can help make the ticks look pretty...see ?par.
Or use various functions from the package `plotirx': axis.break and
gap.barplot might be helpful.
For those functions, you'll probably need to get your frequencies

Try replacing a space followed by anything (.*) with the empty string:
x - c(hsa-let-7a MIMAT062 Homo sapiens let-7a,
+ hsa-let-7a* MIMAT0004481 Homo sapiens let-7a*,
+ hsa-let-7a-2* MIMAT0010195 Homo sapiens let-7a-2*)
sub( .*, , x)
[1] hsa-let-7ahsa-let-7a* hsa-let-7a-2*

Two different ways:
library(ggplot2)
x=5
size=50
A=data.frame(X=sample(x, size, replace=T), Y=sample(x, size,
replace=T),a=rep(1:2,each=25));A
# Facetting
qplot(X,Y,data=A) + geom_jitter(position=position_jitter(width=.03)) +
facet_grid(.~a)
# Or with vp
p=qplot(X, Y, data=A) +
M.Ribeiro,
You can install on Windows from the tar.gz using the RTools.
You need to set the PATH to find RTools and it looks like you skipped that
step.
Full details are in the R Extensions manual.
Here are my notes, from several years ago as you can see by the R-2.8.0
paths
and the Rtools29.exe
Hi,
Working on a report that is going to have a large number of graphs and
summaries. We have 80 groups with 20 variables each.
Ideally, I'd like to produce ONE page for each group. It would have two
columns of 10 graphs and then the 5 number summary of the variables at
the bottom.
So, perhaps
Use lattice.
require(lattice)

I have a data frame 10 by 12 with positive and negative numbers. I
want to select only the positive numbers and find the average.
This calculates the average of everything:
av5 - subset(ER9r, Day == 253, select = c (Depth1j:Depth0.75j)
av5 - mean(av5)
I need something along the lines of
Hi,
ggplot2 or lattice could help you in creating the plots. Adding a
summary will however require some play with Grid graphics; either
using gridBase to mix lattice / ggplot2 output with base R graphics
(e.g. textplot() from some package I forget), or you'll need to
produce the textual summary

Lattice looks nice, but how can I put some summary text at the bottom?

You can save as png like this too:
library(ggplot2)
data=data.frame(
X=sample(10,1000,replace=T)
, Y=letters[1:10])
png(mypng.png)
qplot(X, data=data, geom='histogram') + facet_wrap( ~ Y)
dev.off()

Hi Karsten,
There's no easy way to do this because behind the scenes geom_ribbon
uses grid.polygon.

With ggsave the graph windows pops up but using:
png(mypng.png)
qplot(X, data=data, geom='histogram') + facet_wrap( ~ Y)
dev.off()
The graph is saved in the background
Is there a way to hide the graph window when
using ggsave?
You can save as png like this too:

the correct way to do it is
solve_TSP(tsp, 2-opt, control=list(rep=56))

Hi:
A simple diagnostic is to check how many distinct run lengths exist
in a row - ideally, it should be one or two. If it's more than two,
something
is amiss. Hence, define f() as a function to determine the number of
distinct
runs in a given row and call the apply() function with it:
f -
1 - 100 of 123 matches
